本所于1965年3月上旬,曾进行不同紫云英施用量試驗。結果在肥力中下等的稻田,亩施3,000斤茎叶作基肥,水稻亩产达774.6斤。較底肥(对照)增产45.1%,又較施2,000斤、1,500斤、1,000斤綠肥处理分別多收稻谷49.2斤、107.2斤及146.0斤。但随着施用量的增加,其結实率反有下降的趋势,应注意配施磷、鉀肥。 The Institute in early March 1965, had conducted a different amount of milk vetch test. As a result, in the fertile rice fields, 3,000 kilograms of stems and leaves were used as basal fertilizer, yielding 774.6 kilograms of rice per mu. Compared with the basal one (control), the yield increased 45.1%. Compared with the application of 2,000 kg, 1,500 kg and 1,000 kg of green manure, the yield of paddy more than 49.2 kg, 107.2 kg and 146.0 kg respectively. However, with the increase of the application rate, the seed setting rate had the tendency of declining. We should pay attention to the application of phosphorus and potassium fertilizer.
